Basically, Sierra Nevada has been using a cylindrical container to run fermenting wort through to pick up even more essential oils. On a homebrew scale, this is probably impractical, but it's an awesome idea. Kinda like a low temp hopback that you use while the ferment takes place....

I actually did unclog it and I have video.....youtube and photobucket kept failing on me when i tried to upload.

FWIW, I have good video of the unclogging, but I went inside for a second only to hear this "foom!" and I ran back out and it was unclogged. Figures. At least I don't have a worthless $180 chiller anymore.
